ABSTRACT Precisely and controllably engineering the pore structure of carbon nanomaterials plays a vital role in achieving desired properties and thereby boosting their performance in diverse fields, while it still remains a huge challenge owing to the remarkable growth of structural complexity. In this study, we successfully explore a quantitative dual‐template‐mediated co‐assembly strategy to accurately achieve continuous structural transition of hierarchical porous carbon nanospheres across a broad scope of pore architecture. Specifically, this simple but powerful strategy can realize meticulous control over the reaction system's co‐assembly behaviors and further quantitatively manipulate structural parameters of the derived nanospheres by adjusting the packing parameter p . Impressively, the dynamic structural transformation process of the resultant carbon nanospheres resembles a flower‐blossoming process. Under optimal synthesis conditions, the obtained flower‐like carbon nanospheres feature a hierarchical pore system composed of micro‐/meso‐/macropores, high surface‐to‐volume ratio, abundant active sites, rich heteroatom doping, and fast transfer dynamics, thereby delivering ultra‐high electromagnetic wave absorption performance. Our study establishes a customizable and programmable platform for engineering a variety of hierarchical porous nanostructures, unlocking distinctive properties for advanced applications.
